wat lpm fir shielding gas welding titanium?

haven't figured how to attach pics yet, but about to undergo first titanium welds. got chamber built, jus need to purchase gloves and rings to seal gloves to chamber. all thats left is finding flow rate of shielding gas and steady hand for the execution. looking forward to input and ill post again thru out process

I think you mean CFH but anyways. I used to turn my chamber purge on at around 10 CFH and my torch set to 15 CFH, try it on a test piece first and make sure you have no oxidation of the weld or HAZ (heat affected zone). If you have any oxidation bump up your chamber CFH a bit. What size gas cup are you running?

It is the same thing but in metric

L/PM Litres Per Minute

A litre is a Volume measurement already

CFH- Cubic Feet per Hour

a foot is not a volume so we have to then state it as a Cube to show volume.

Most likely your regulator gauge has both measurements on the dial- at least all of the ones I have do.
